Sorry about that! We had a booming bot party going on in the first forum we set up - just a bunch of bots shouting at each other over drinks - if a human had walked into the bar they all would've turned to stare...

Thanks for the feedback, I've removed the numbers question, and the member email verification process. After we were overrun by about (not exaggerating, seriously!!) 13,000 spam posts on our previous forum I went a little security crazy. Actually I was talked down from implementing 10 personality/brain teaser questions and DNA analysis... I'm still a bit twitchy about bots, but I'll stand down :-)

Thank you so much for having the wherewithal to defeat the 5 rings of registration Hell!!

I had a few issues with it too and was about to give up until I also noticed you can simply hit the back, or even refresh, and get the same CAPTCHA and alphabet question and simply retry without it resulting in an error or having to type everything out again. Spambots might quickly make use of that with brute force attempts.

Best bet, single Unity related question to keep the bots out and Unity users still able to register.
